Were following breaking news on the investigations of the president. Mr. Trump dodging questions tonight about a Top Democrats new demand for his tax return telling reporters that the parties involved with have to speak to his lawyers. This as the House Judiciary Committee chairman is asking the attorney general release any summaries of the Mueller Report prepared by the special counsels office, a source confirming that it was expected to use more of the material that be the fourpage letter. And now boeing accepting responsibility for the two crashes, disasters that killed 346 people. The companys ceo declaring we own it. This hour ill talk with Richard Blumenthal and our correspondents and an lists are also standing by. First, lets begin with jim acosta. Lists are also standing by. First, lets begin with jim acosta. We heard from the president as the pressure clearly builds for the release lease of the Mueller Report and his tax returns. Reporter thats right, two fronts that the president is playing against on. President trump is blasting reports that Robert Muellers members of his team are unhappy with William Barrs sum rift se conclusions. But that is hardly the end of the president s headaches. Democrats are now making a move for President Trumps tax returns. The president just a short while ago telling reporters, talk to my lawyers. Now that investigators have complaining that William Barrs letter go too far in clearing President Trump, anger is building at the white house. The president tweeted his theory. There is nothing that we can give to the democrats that will make them happy. Is this the highest level of president happen harassment in the history of our country. Sarah sanders lashed out at news reports about the frustrations inside muellers team. You mean the Anonymous Sources that allegedly linked confidential information . I have full confidence in the attorney general and his assessment. Reporter but on capitol hill, support is building with Charles Grassley tweeting i support release of the Mueller Report. There is an easy answer. Rae release the Mueller Report as soon as possible. And it will be released. Just a question to us it is inevitable, to them it is inconceivable. Reporter convinced mr. Trump is hiding something, House Democrats are also making a request for six years of his tax returns, a secret he has closely guarded. This is likely to wind its way through the federal court subpoena and we wanted to make sure that the case constructed would stand up. Reporter and the president side stepped the question. Speak to my lawyers, interest he to the attorney general. Reporter the president has repeatedly beat back efforts to obtain the tax returns claiming they are under audit. Ive ordered it every single year and you dont discuss anything. Im releasing when were finished with the audit. I have to say the irs is very professional. When the audit is finished, i will release it. As ive told you, they are under audit, they have been for a listening timing. They are extremely complex. People wouldnt understand them. Reporter but fellow republicans are starting to break from the president. I think all things being equal, i would like to see the president s taxes. I wouldnt be a verse to turning over my taxes. Reporter the president is backing down when it comes to shutting downs border. Now he says he will get mexico one year to crack down on migrants. Well give them a one year warning and if the drugs dont stop or lanlgly stop, were going to put tariffs on mexico and products in particular are cars. The whole ball game is cars. It is the big ball game. And if that didnt stop the drugs, we close the border. Reporter the president is allowing mexico more timing to solve the problem despite calling it a National Emergency once again. I hate to see it, but at least i can say i was right pip told everybody, you have a National Emergency at our border. Reporter as for the Mueller Report, one Administration Official expressed frustration with democratic demands to see as much as possible of the report. The official complained that the report should not reveal information that is embarrassing about the president if he is not being being accused of committing any crimes. In the words of this official, that possibility rhymes with the word gritty. I cant say the shull woactual tv. Jim, thank you very much. Lets get more now with the Congressional CorrespondentPhil Mattingly joining us. So what is jerry nadler looking for . Reporter it seems like each day the tension between the top democrat and the Justice Department only seems to grow. The latest escalation coming in the wake of those news reports about frustration. Some special counsel investigators and revelation that they had prepared summaries that they wanted to be used or potentially sent out to characterize the report. Jerry nadler the top democrat on the committee, chairman, saying in a three page letter to the Justice Department attorney general bill barr, quote, these reports suggest that the special counselwn summaries which you chose to with hold in favor of your own. We request that you produce to the committee all communications between the special counsels office and the Department Regarding the report. The big issue is whether or not the Justice Department will respond affirmatively to what the committee has asked. Keep in mind the Justice Department has made clear that they are essentially scrubbing the report, trying to take out grand jury information. What democrats where saying, they want a response immediately. The Justice Department did put out a statement this morning saying the reason that they didnt release anymore information than the four page letter is because each page of the report was marked confidential and therefore could not be released, but that has not been enough for democrats and it just continues what weve seen over the course of the last couple days, democrats continuing to put pressure on the attorney general, trying to get a sign that they will get the full unredacted report plus all the underlying investigative material. Jerry nadler was given the authorization to subpoena the report, something that he said that he is willing to do in short order but willing to give the attorney general time to try to comply without that subpoena. I will note as you look at the shear scope of the investigations that are going after the Trump Administration from House Majority democrats here, there is also one other thing you need to keep in mind with the Mueller Investigation, special counsel and whether or not he will testify. Take a listen i think it is inevitable that mr. Mueller will testify at some poipd, but t point but first thing is we need release of the report and documents. Reporter and that tracks with what ive been hearing from democrats in the house and senate. It is not an if the special counsel will come testify publicly, it is a matter of when. How and when is an open question. But add that to the list of the pressure put on to get the public release of that Mueller Report as soon as possible. As we know, the Justice Department has made clear that they believe the report in redacted form will be released in mid april. The attorney general says that he will testify. Well see if the special counsel will as well. We certainly will. Phil mattingly, thank you. And now just into cnn, the new move by Michael Cohen former trump lawyer and fixer is offering additional assistance to congress as he is preparing to go to prison next month. Pamela brown is here. What are you learn something. We have learned from this t letter that Michael Cohens attorneys have said just before he is to report to jail, Michael Cohen has found a hard drive with millions of files according to this letter from the attorneys. And the letter says mr. Cohen was only recently able to access a hard drive and said drive contains over 14 million files which consist of all emails, voice recording and attachments from his computers. He has only time to question through less than 1 of the drive or approximately 3500 files. Mr. Cohen needs time, resources an assistance to separate out privileged and personal documents from the 14 million files to make the rest available for review by various congressional committees that have south oght his help. So they are trying to make the case to write a letter on cohens behalf saying they need his continued koor cooperation that these committees still need his help. And this is a bid in order to delay his jail time. It lays on out here right on the last page of the letter that Michael Cohen wants sdny to advocate for him to delay the jail time. Of course he is supposed to report early in may. And also Michael Cohens team is asking for reduced jail time as we know his sentence has been delayed one time. And so now this is an effort to try to get congress to get to his side to help him reduce his sentence. He has a three year sentence supposed to begin next month. Stand by. Want to bring in jeffrey toobin. Youve gone through the letter. What do you think . The key thing to remember about Michael Cohens legal situation is that he is going to prison for crimes he committed for the benefit of donald trump. If you look at what pleaded guilty to, lying about the timing of the trump tower moscow negotiations, the Illegal Campaign contributions to stormy daniels, the situation with Karen Mcdougal and the national enquirer. All of those crimes were not for him, but the benefit of donald trump and he is making the point that if you want me as a witness, you need me here in knock or are in washington, not locked up in prison because i wont have access to those commuters, and i dont and i cant help you. Now, the complexity is it is not up to congress when he has to surrender, it is up to the Southern District of new york and the court who is supervising his case. But it is a pretty compelling case that if you want the information, i can only get it for you if im out of prison. And i also think we should make clear, if i may jump in, we dont know how helpful these 14 million files are going to be. Correct me if im wrong. He is saying look, ive found this hard drive with all these files. We dont know if the information might be helpful to investigators or making the case that he has only been through 1 and he doesnt have enough time before jail to go through the rest of this, so please give him more time to do so. And lets not forget Michael Cohen didnt have a Cooperation Agreement with the sdn ychltsdn. So in inside sense h in essene his time is trying to get the benefit of one without having had one. I think like every person he wants to be sentenced to less timing. And three years for a series of crimes like he pleaded guilty to, that was a stiff sentence if you look at comparable situations. Although nothing is precisely comparable. And there is the possibility of a reduction and it is true that there is no guarantee that these documents will produce important or incriminating evidence. But the one thing for sure is if he is sitting in otisville or one of the other federal prisons, he cant go through it and congress is guaranteed that they wont learn the contents of what is inside. As you know, last time cohen testified before congress and we were all watching it, he seemed to open up several new potential areas of inquiry. Do you believe congress would be interested in going through this Additional Information he has now himself going through . I am Certain Congress is interested in following up on information like the possibilities of bank fraud, of Insurance Fraud which he expoliexpli explicitly ra lly raised before congress. But it is not up to congress when he reports to congress. That is an issue for the Southern District and the courts. And he is due on may 6th. Just about a month from today. So all of this if anything is going to change is going to have to change quickly. The two things he would like to get a reduced prison sentence, he is about to start three years in jail. And he wants the beginning supposed to be next month to be stacksly postponed. Would a letter to the Southern District, to the u. S. Attorney for the Southern District of new york help Michael Cohen in those two objectives . One but not the other. I think that there is realistic possibility that the sentence could be delayed. Lots of people sentenced to prison manage to put off their sentences f sentenc sentences for several months. A reduction in the sentence is a different story and that is something that would absolutely have to come from the southern dwrikts of new yo district of new york and not from congress. So that is the audience that he needs tos to persuade on reduc. All right. Well see what happens. And there is other breaking news were following this time on the boeing 737 max disasters. The companys ceo now admitting that an automated flight system known as mcas played a role in the crashes. The chief says that it is the aerospaces giant responsibility to eliminate it. And they say 346 were killed and our Senior Correspondent drew griffin is just outside seattle where max outliners are being built. What else are you learning . Reporter the admission came after the ethiopian preliminary report that really pointed a finger at boeing, its new plane and the design of that plane which nights to be fixed according to the ethiopians. No 737 max should go up in the air until boeing fixes its Software Problem and proves to the world that it wont happen again. Are the tonight t tonight the ceo of boeing accepting blame for two much its airlines that crashed. It is apparent that in both flightses maneuvering characters ris ib its augmentation system known as mcas acted in response to erroneous information. It is our responsibility to eliminate this risk. We own it and we know how do it. Reporter the video message from boeing comes after a devastating preliminary report released today laying out that Software Issue apparently caused the crash of an Ethiopian Airlines flight last month. The report also suggesting the same issue may have caused the lion air flight to go down last year. The preliminary report finds the pilots did everything required to try to bring the plane back safely, but ultimately couldnt control it. A former boeing operations analyst says during development of the 737 max, boeing had a mandate, make sure any changes to the plane would not require additional Pilot Training in a simulator. Unprecedented. Never happened in the past that im aware of. We were very uncomfortable with this. Reporter he says boeing managers told him they oechb sold the plane to Southwest Airlines with a guarantee, a rebate of 1 million per plane if sim uhe to Simulator Training was required. The demand known as level d took over design of the aircraft. Throughout the design iteration, that was something that was always asked. You know, are we risking level d. And if you are, you have to change it. I think philosophically it was the wrong thing for the company to do, to mandate such a limitation. To strongly avoid it, makes sense. But to prevent it, i think you can see the line from that to these accidents. Reporter federal investigators are now trying to determine if boeings costsaving moves could somehow lead to criminal charges. Neither boeing nor southwest would respond to questions about the business deal raised in our story. As for the software fix itself, boeing was expect expected to dl deliver that to the faa last week, but there was a glitch, if you will, that boeing is now trying to fix. But any delivery of that software is still apparently weeks away. Drew griffin, thank very much. Joining us, senator Richard Blumenth blumenthal. You were one of the first u. S. Lawmakers to call for the grounding of that boeing 737 max plane here in the United States. You just heard the boeing ceo chairman apologize saying they now own this crisis. How significant is this . This preliminary report from the ethiopian authorities is profoundly significant and left the boeing ceo with really no choice but to acknowledge that it is on them and reaffirms the reason that i sought the grounding right away. The pilots did everything that they were spoeged to do. They did Everything Possible and they struggled with the software. And the fault really is not only on boeing but also on the faa which outsourced safety. Did it on the c
